Compatibility With Gutenberg Full Site Editing
Full-Site-Editing is the ability to edit all elements of a site including header, page content and footer using Gutenberg blocks. With Full-Site-Editing, you can now edit both an individual post’s content and, with the release of Gutenberg 9.6, the template that an individual post uses.
If you want to build your site with Gutenberg then please make Full Site Editing option enable in theme option to use FSE.
Porto is compatible with FSE and we provide several header elements for users.
In Porto, Gutenberg Shop 4 is built by FSE.
